Patent CA-2248910-A1 (CA)
Title: Dispensing system and method for dispensing an aqueous solution
Inventor: TRANG DUY KHANH
IPC: B24B37/04
Filed: 1998-10-02
Abstract: A system and method for dispensing an aqueous solution to one or more points of use is provided with one or more pressure vessels that are adapted to be charged with pressurized gas to drive the aqueous solution on to the point or points of use. A humidifier is also employed to humidify the pressurized gas to at least inhibit the pressurized gas from evaporating the moisture from the aqueous solution. In such manner, changes to the make up of the aqueous solution are avoided. Such changes can produce caking and/or changes in chemical properties found in pressure vessels used in dispensing slurries.

Title: Method and system for joint timing recovery and channel estimation for dmt modems
Inventor: HO JIN-MENG
IPC: H04J11/00
Filed: 1998-10-26
Abstract: A method and a system for acquiring data frame timing in a discrete multitone modem system in which an acquisition frame is generated having a first predetermined number of impulse signals. Each impulse signal is spaced in time by 2(P + 1)T s, such that 1/T s is a sample transmission rate, and P is a time length in samples of a cyclic prefix that is added to a data frame. The cyclic prefix length P is chosen such that a channel impulse response seen at a receiver effectively spans no more than P + 1 samples when a received signal is sampled at the 1/T s rate. Data frames are generated subsequent to the acquisition frame. Each data frame includes a cyclic prefix and at least as many data samples as samples of the cyclic prefix. The acquisition and data frames are converted to an analog signal for transmission. The received acquisition frame is sampled and a summation window is advanced one sample at a time through the received acquisition frame. The sampled acquisition frame is summed over each summation window, with each summation window spanning P + 1 samples of the acquisition frame. A maximum summation value is determined as the summation window advances, and a data frame boundary is determined based on the summation window corresponding to the maximum summation value. A channel impulse response is estimated based on the P + 1 samples of the received acquisition frame corresponding to the maximum summation value, and data is coherently detected based on the estimated channel impulse response.

Abstract: L'invention concerne un système de freinage dans lequel un ressort (3) monté dans un boîtier (2) agit avec une force de ressort sur un plateau support (4) mobile et le maintient dans une position de freinage, des garnitures de frein (5) montées sur le plateau support (4) étant comprimées contre un disque de frein (6). Un entrefer (7) entre le boîtier (2) et le plateau support (4) correspond au trajet parcouru par le plateau support (4) guidé à l'aide de broches-guides (8) périphériques, après désactivation d'une bobine (9) placée dans le boîtier (2). Lorsque la bobine (9) est activée, sa force électromagnétiue agit à l'encontre de la force du ressort. Le plateau support (4) est alors amené en position de repos, contrôlée par un microcommutateur (10). Pour contrôler la position du plateau support (4), il est prévu un potentiomètre (11) muni d'un curseur (12), déplacé à l'aide du plateau support (4). La résistance de sortie du potentiomètre (11, 12) varie ainsi de manière linéaire avec le mouvement du plateau support (4).

Patent CA-2268617-A1 (CA)
Title: Homogeneous binding assay
Inventor: HANSEN W PETER
IPC: G01N33/543
Filed: 1998-01-23
Abstract: A homogeneous method of measuring chemical binding relies on resonant, or "amplified", optical extinction (light scattering plus absorption) from a defined, specific class of colloidal particles wherein the real term n of the complex refractive index n-ik approaches zero while the imaginary term k approaches 2. Chemical binding partners are coated onto the particles, which either aggregate or disperse during the binding reaction, causing an optical extinction change at one wavelength that is quantitatively related to the number of single colloidal particles and another at a second wavelength that is quantitatively related to the number of doublet colloidal particles. The method employs: (1) a specific class of colloidal particles that exhibit optical resonance and that are substantially smaller in diameter than a wavelength of visible light; (2) a one-step process of colloidal particle aggregation; and (3) a photometric extinction measurement at wavelengths where the particles exhibit optical resonance.

Patent CA-2276191-A1 (CA)
Title: Hash-based translation method and apparatus with multiple level collision resolution
Inventor: POOLE NIGEL T
IPC: G06F12/10
Filed: 1997-12-30
Abstract: A translation is performed by using a programmable hashing technique on an input number to generate a hashed number (408). A subset (410) of the hashed number bits are used to index a first hash table (420). In first hash table locations (426) where a hash collision does not occur, the first hash table entry (426) contains an index (for IDX) into an output (438) table which contains the desired translated output number (436). In first hash table locations where a hash collision occurs (424), the first hash table entry (494) contains a pointer (NTI) to a first resolution table area in a second hash table. The first resolution table area contains entries which are indexed by additional bits selected from the hashed number in accordance with a mask field in the first hash table location. If collisions occur in the resolution table a new resolution table is created and the process is repeated. The resolution process thus proceeds in stages until all input numbers have been translated.
